Summary
# Editorial Summary: Morphometric measurements of the feet of working donkeys Working donkeys carry disproportionate loads relative to their body size, yet objective data on their normal hoof anatomy have remained sparse—a significant gap for farriers and veterinarians managing these animals in demanding working conditions. Mostafa and colleagues measured thirteen distinct parameters across the front and hind feet of twenty healthy Egyptian working donkeys, including hoof dimensions, angles (toe, heel, hoof–pastern axis and coronary band), and weight-bearing geometry. Front hooves proved substantially larger and more rounded than hind feet, whilst medio-lateral balance and toe–heel ratios aligned with equine health standards; notably, all animals exhibited a broken-forward hoof–pastern axis, suggesting this may represent normal donkey conformation rather than pathology. Strong positive correlations emerged between estimated body mass and hoof width in both fore and hind feet, establishing a quantifiable relationship for predicting appropriate hoof dimensions based on individual donkey size. These baseline measurements offer practical reference points for trimming protocols and hoof management strategies specific to working donkeys, though the authors appropriately emphasise that longitudinal studies are needed to determine whether broken-forward axes reflect inherent conformation or adaptive responses to workload.

Practical Takeaways
- •Donkey hooves have naturally different proportions and angulation than horses—don't apply horse trimming standards directly; a broken forward hoof pastern axis appears normal for donkeys
- •Use body weight as a practical guide to expected hoof width when assessing whether a donkey's feet are appropriately sized and balanced
- •These baseline measurements provide reference values for assessing foot balance and soundness in working donkeys, though individual variation should be expected
Key Findings
- •Front feet of working donkeys are more rounded and significantly larger than hind feet
- •Medial-lateral balance and toe-heel angle ratios in donkeys fall within recommended healthy guidelines for horses
- •Broken forward hoof pastern axis is characteristic of donkeys, differing from horse conformation
- •Significant positive correlation exists between estimated body mass and hoof width in both front and hind feet
